WATER-FILTER.

SPECIFICATION forming part of Letters Patent No. 628,517, dated July 11,1899. Application filed September 20, 1898. Serial No. 691,46 8 Wemodel.)

To to whom, it may concern:

Be it known that we, DWIGHT J. BLIss and EDWARD J. RICHMOND, citizens ofthe United States, residing at Carthage, in the county of Jasper andState of Missouri, have invented certain new and useful Improvements inWVator-Filters; and we do declare the following to bea full, clear, andexact description'of the invention, such aswill enable others skilled inthe art to which it appertains to make and use the same.

Our invention relates to improvements in water-filters, and moreparticularly to that class of which the .filter forming thesubjectmatter of Letters Patent No. 611,426, granted to us on the 27thday of September, 1898, may,

be taken as a type; and the objects of the presentinvention are tosimplify and improve the construction and increase the efficiency of thefilter. i

To this end the invention consists in the construction, combination, andarrangement of the device, as will be hereinafter more fully described,and particularly pointed out in the claims.

The same reference characters indicate the same parts of the inventionin the several views.

Figure 1 is a vertical section of ourimproved water-filter; Fig. 2 is ahorizontal section on the line 2 2, and Fig. 3 is a similar view on theline 3 3.

1 denotes the base provided With the supporting-legs 2 2. 3 denotes thecylindrical shell removably secured to the base 1, so as to form awater-tight joint, and 4 denotes the fixed filtering-cylinder,which issupported between the collars 5 and 6, fixed to the vertical inlet-pipe7.

A cylindrical cage, consisting of the top and bottom disks 8 and 9,connected by vertical parallel bars 10 10 and 12 12, encompasses thefilter-chamber and is adapted to revolve freely about it in eitherdirection, the rotation of the cage being effected by the yoke 12}, theparallel depending toes 14: 14 of which engage the orifices 15 15 in thetop disk 8. The axial shaft 16 of said yoke extends through astuffing-box in the top of the shell and terminates in a detachablecrank-handle 17, by means of which said cage may be rotated.

To the vertical cage-bars 1O 10 are fixed the springarms 18 18, the freeends of which carry a vertical shoe 19, which is secured to a strip orslab of stone 20, the inner face of which bears against the periphery ofthe filtercylinder 4.

21 denotes a V-shaped scraper formed with parallel arms 22 22, which arehinged in the vertical bars 12 12 to permitthe parallel edges of thescrapers to bear against the filter-cylinder 4, and 23 23 denoteU-shaped springwire yokes, the upper ends of the parallel arms of whichare turned inwardly to form the lugs 24: 24, which engage correspondingorifices25 in the shoes and scrapers to press them firmly against thefilter-cylinder.

The water enters the filter through the inletpipe 7 and fills the shell3, thence passing through the porous walls of the filter-cylinder 4;into the filtered- Wat-er chamber 26, formed between the inside walls ofthe filterchamber, from whence it is drawn for use through the valvedoutlet-pipe 21.

28 denotes the valved Waste-pipe communicating with the water-spacebetween the shell 3 and the filter-cylinder 4:. I

The operation is as follows: The water to be filtered is admittedthrough the inlet-pipe 7 into the space between the cylinder at andshell 3, so as to completely encompass the cylinder 4:, the pressureforcing the water through the cylinder and into the chamber 26, whenceit is drawn through the outlet-pipe 27, the organic matter andmechanical impurities being separated from the water and retained on theoutside of the filter-cylinder 4. hen the surface of this cylinderbecomes foul or clogged up, the waste-pipe 28 is opened and the cagerevolved by means of its handles, which carry the stone slabs andscrapers, around the cylinder 4:, so as to effectually remove the slimeand organicmatter from the outside wall of the cylinder, so that it maybe carried out through the waste-pipe.

Although we have specifically described th construction and relativearrangementof the several elements of our invention, we do not desire tobe confined to the same, as such changes or modifications .may be madeas clearly fall within the scope of our invention without departing fromthe spirit thereof.

Having thus fully described our invention,

inder, of the rotating cage having its upper 15 end formed withretaining-recesses and the yoke adapted to engage said recesses and r0-tate the cage, substantially as shown and described.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
